syncing-docs-and-memory

Ceremony-free, bidirectional sync between project docs and memory systems.

• Docs side: README / AGENTS.md / CLAUDE.md / SPEC.md / CONTRIBUTING.md / ARCHITECTURE.md and any other discovered *.md
• Memory side: Serena MCP automatically; gstack-learnings / gbrain / Notion / Obsidian / Inkdrop / Codex / local .context/ only when the user opts in via speech ("Notion も同期して" etc.)
• NOT in scope: CHANGELOG, VERSION, PR body, release ceremony — use /document-release for those
